WASHINGTON — Tea Party favorites such as Ted Cruz and Rand Paul stand out in the group of 18 Republicans who voted "no" on the bipartisan Senate deal to reopen the government and temporarily raise the debt limit.

The opponents of the deal are an interesting mix, representing well-known fiscal conservatives, longtime Senate veterans and critics of President Obama's health care law

Cruz of Texas, Paul of Kentucky and Sen. Marco Rubio of Florida are all considered potential 2016 presidential candidates. Joining them in rejecting the deal were Sens. Mike Lee of Utah, Ron Johnson of Wisconsin and Pat Toomey of Pennsylvania, who were all elected with Tea Party support.

The final Senate vote was 81-18. Sen. James Inhofe, R-Okla., did not vote because he is recuperating from heart bypass surgery.

Cruz, still in his first year in the Senate, is now best known across the country for his 21-hour protest of Obama's health care law, which helped touch off the budget stalemate that led to the shutdown. Cruz and Lee were the leading proponents in the Senate of trying to defund Obamacare and tie it to the stopgap measure to fund the government.

Sen. David Vitter, R-La., who tried unsuccessfully to attach a health care provision to the stopgap spending bill that funds the government, was another "no" vote. Vitter wanted to make sure that members of Congress pay the full cost of their health care.

Sen. John Cornyn of Texas, the Senate minority whip, was among those who rejected the deal that was reached between Senate Majority Leader Harry Reid and Minority Leader Mitch McConnell. Cornyn, McConnell's top lieutenant and the No. 2 GOP leader, is up for re-election next year.

Sen. Mike Enzi, R-Wyo., also voted "no." He is being challenged in a GOP primary by Liz Cheney, a daughter of the former vice president, who has criticized him for not being conservative enough.

Longtime Senate veterans such as Tom Coburn of Oklahoma, Chuck Grassley of Iowa, Pat Roberts of Kansas, and Richard Shelby and Jeff Sessions, both of Alabama, also voted against the shutdown/debt deal. They're all well-known fiscal conservatives.

Rounding out the list of GOP "no" votes were Sens. Mike Crapo and Jim Risch, both of Idaho; Dean Heller of Nevada and Tim Scott of South Carolina. Scott, who was appointed to the Senate, was endorsed by Tea Party groups when he was elected to the House in 2010.
